it sure sounds like u gonna beat a jack to death... so u may really want to side with a really good jack.. maybe snap-on or other good tool companies... i have a H/F with no problems, then again i don't use it often. if a quality jack cost $600 bucks u can buy about 8 H/F jacks for the same money.. if they last 5 yrs apiece thats 40yrs of use....long time.. coin toss....
